Disc brake upgrade

I finally took the plunge and upgraded the stock V-brakes on my Trek mountain bike to Avid BB7 disc brakes. It really was straight forward and final adjustment of the calipers was a breeze. The only parts required for this project were 2 new disc-compatible wheels, front and rear brake kits, and a special rear disc adaptor for my 2002 Trek (2001-2005 Trek models require a special adaptor for the rear frame which the rear caliper then bolts directly to). I now have two 26" Matrix 750 wheels and nice set of Promax V-brakes available with only 300 miles on them if anyone is interested!

Here is a link to the new wheels:

I love disc brakes. I have BB5's and am more than satisfied with them. It's hard for me to feature having a bike without them.
It's all downhill from here. Except the parts that are uphill.

I still want disc's for my road least on the front. (see thread about going downhill fast)

Before disc's on the MTB I used to have trouble dismounting the tires because they were melted to the rim...

That reason for having disc's doesn't get mentioned very often.

I have Hayes Nine hydraulic on my FS MTB and I will never go back. They are superior in every way to any brake system I have used. Two years now, no parts, no adjustment, no problem.

This month Cycling plus magazine reviewed the Orbea Diem Drop Disc. It is a carbon framed roadie with disc brakes. I think we will soon see a time when all the manufacturers have at least one road model that has discs. For those of us who have had to try and cobble together the pieces (I remember searching for a carbon fork with disc tabs when they were few and far between) on our own; this will be great news.

Ouch. You point out a big hole in my bike mechanic experience. Of the 4 dozen or so buildups in the last few years I have yet to touch a disc brake set. Strange. Ouch.

But you've given me an idea... I'm rebuilding an old tandem and "brakes" are an issue, as is the potential replacement of the front fork (strangely sized french fork and headset). Maybe there is a disc brake solution waiting to be discovered there...
